Of course, there is the GA evolved antenna. https://en.wikipedia.org/wiki/Evolved_antenna https://en.wikipedia.org/wiki/Evolved_antenna

  Slightly related, an FPGA circuit designed by a genetic algorithm which ended working due to analogue effects and hardware-specific magnetic flux interference. https://www.damninteresting.com/on-the-origin-of-circuits/ https://www.damninteresting.com/on-the-origin-of-circuits/

    It makes you wonder if it would be useful to create a programmable circuit where such analogue effects are the intended working principle.

  For this or other successful genetic algorithms, it would seem clear you still can’t know if it’s an optimal design simply because in most cases the number of designs tested would be a small fraction of the possible designs. However, things like useful sound recognition being done with only a small number of logic gates (commenter below provided a nice article, thank you) make it hard to imagine doing much better. I wonder if the process can be shown theoretically to offer any help in guaranteeing minimum bounds w.r.t. the optimal case, even if can’t be fully proven to be optimal.
